Background: GAS6(Growth arrest-specific 6), also known as AXLLG or AXSF, is a human gene coding for the Gas6 protein. It is mapped to 13q34. GAS6 was originally found as a gene upregulated by growth arrested fibroblasts. This gene product is a gamma-carboxyglutamic acid(Gla)-containing protein which thought to be involved in the stimulation of cell proliferation, and may play a role in thrombosis. What's more, the product of the GAS6 gene, a ligand for the AXL, MER, and TYRO3 tyrosine kinase receptors, is a vitamin K-dependent protein, structurally related to anticoagulant protein S but lacking its anticoagulant activity. This protein also shows great importance in the cardiovascular system.

Application Details

Before using Kit, spin tubes and bring down all components to bottom of tube. Duplicate well assay was recommended for both standard and sample testing.

Comment

Sequence similarities: Contains 4 EGF-like domains.

Plate

Pre-coated,Strips (12 x 8)

Protocol

mouse GAS6 ELISA Kit was based on standard sandwich enzyme-linked immune-sorbent assay technology. A monoclonal antibody from rat specific for GAS6 has been precoated onto 96-well plates. Standards(NSO, D115-P673) and test samples are added to the wells, a biotinylated detection polyclonal antibody from goat specific for GAS6 is added subsequently and then followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with PBS or TBS buffer. HRP substrate TMB was used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the mouse GAS6 amount of sample captured in plate.

Assay Procedure

Aliquot 0.1 mL per well of the 2000pg/mL,1000pg/mL, 500pg/mL, 250pg/mL, 125pg/mL, 62.5pg/mL, 31.2pg/mL mouse GAS6 standard solutions into the precoated 96-well plate. Add 0.1 mL of the sample diluent buffer into the control well (Zero well). Add 0.1 mL of each properly diluted sample of mouse cell culture supernates, serum or plasma(heparin, EDTA) to each empty well. See "Sample Dilution Guideline" above for details. It is recommended that each mouse GAS6 standard solution and each sample be measured in duplicate.
